Purpose of the Study:

• To investigate Raman spectroscopy (RS) for label-free, non-invasive identification of nutrient components in rice grains.
• To assess the potential of RS for fast and accurate identification of 15 different rice genotypes.

Main Methods:

• Utilized Raman spectroscopy (RS) for label-free, non-invasive analysis of intact rice seeds.
• Analyzed grains from 15 distinct rice genotypes.

Main Results:

• Spectroscopic analysis of intact rice seeds enabled accurate rice variety identification in approximately 86% of samples.
• Demonstrated the potential of RS for rapid and precise nutrient component analysis in rice grains.

Conclusions:

• Raman spectroscopy (RS) is a viable technique for accurate rice variety identification.
• RS can be employed for fully automated, fast, and accurate identification of seed nutrient components, supporting digital farming initiatives.
